Investment Objective
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund seeks long-term capital appreciation.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Fees and Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>Shareholder Fees (fees paid directly from your investment) </b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) </b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Example of Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that operating expenses remain the same as in the tables above. The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 32% of the average value of its portfolio.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small- and medium-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-and medium capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small- and medium-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small and medium capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Value Style Investment Risk.</b> Value stocks may lose value and may be subject to prolonged depressed valuations.</p>

Fees and Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>Shareholder Fees (fees paid directly from your investment) </b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) </b></p>

Example of Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that operating expenses remain the same as in the tables above. The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 16% of the average value of its portfolio.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research.

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Currency Transactions Risk</b>. Foreign securities are often denominated in foreign currencies. As a result, the value of a Fund's shares is affected by changes in exchange rates. Use of hedging techniques cannot protect against exchange rate risk perfectly. If the Fund's adviser is incorrect in its judgment of future exchange rate relationships, the Fund could be in a less advantageous position than if such a hedge had not been established.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We utilize a long-term focus that is intended to take advantage of investment opportunities presented by what we believe are short-term price anomalies in high-quality stocks. We seek to identify companies with established operating histories, financial strength and management expertise, among other factors. We seek stocks that are trading at a discount to what we believe are their estimated intrinsic values. Fundamental research is performed to identify securities for the portfolio with one or more catalysts present that will unlock the intrinsic value of the securities. These catalysts may include productive use of strong free cash flow, productivity gains, positive change in management or control, innovative or competitively superior products, increasing shareholder focus, or resolution of ancillary problems or misperceptions. We may sell a holding if the value potential is realized, if warning signs emerge of beginning fundamental deterioration or if the value is no longer compelling relative to the alternatives. We may invest in any sector, and at times we may emphasize one or more particular sectors.</p>

Fees and Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund.</p>

Example of Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that operating expenses remain the same as in the tables above. The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>

Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 78% of the average value of its portfolio.</p>

Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small-capitalization companies.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. The securities in which we invest include common stocks, securities convertible into common stocks and, subject to special limitations, rights or warrants to subscribe for or purchase common stocks. We also may invest to a limited degree in non-convertible debt securities and preferred stocks. Furthermore, we may use futures or options to manage cash.
We actively manage a diversified portfolio of securities of companies that we believe can generate above-average earnings growth and reasonable valuations relative to the company's historical position and competitive peer group. We use a bottom-up fundamental research driven process in our stock selection. In selecting securities for the Fund, we focus on three categories of issuers: (i) companies that have a strong potential for growth that we believe has not been entirely reflected in the stock price; (ii) companies that have a moderate potential for growth, but have recurring revenues, earnings or cash flows and a greater potential for relative stock price stability during periods of market turbulence; and (iii) companies that have experienced a disruption in growth but that have implemented changes that we believe position them for strong potential future growth.
We may reduce or eliminate exposure to a stock when we identify a more attractive investment opportunity, or when a company's fundamentals change (product failure, change in management, margin compression and/or change to the competitive landscape). We will also consider selling a stock if the stock's price target has been met.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Futures Risk.</b> Because the futures utilized by a Fund are standardized and exchange-traded, where the exchange serves as the ultimate counterparty for all contracts, the primary credit risk on futures contracts is the creditworthiness of the exchange itself. Futures are also subject to market risk, interest rate risk (in the case of futures contracts relating to income producing securities) and index tracking risk (in the case of stock index futures).</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We look for significantly undervalued companies that we believe have the potential for above average capital growth with below average risk. Rigorous fundamental research drives our search for undervalued, high quality companies; which we define as industry leaders with strong balance sheets and superior cash flows. We utilize quantitative screens to narrow the investment universe by assessing companies' financial statement strength and looking for high cash flows and low financial leverage. Through detailed qualitative research we then identify stocks valued below their estimated intrinsic value with hidden opportunities for above-average appreciation. Typical investments include stocks of companies that have low price-to-earnings ratios, are generally out of favor in the marketplace, are selling significantly below their stated or replacement book value or are undergoing a reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock's price nears its intrinsic value appreciation target, the macro environment becomes unfavorable, short-term downside risks increase, the company's fundamentals have deteriorated or we identify a more attractive investment opportunity.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The core of our research process is the rigorous analysis of each portfolio candidate to identify superior opportunities in each of three categories: First, we develop a strong multi-year investment thesis for each company. Next, we identify catalysts that will drive long-term sustainable earnings growth in excess of current market expectations. Lastly, we look for attractive valuations that do not fully reflect the company's long term growth potential. Once each of these three categories is satisfied (thesis, catalysts, and valuation), a company is added to the portfolio. We sell stocks if our thesis or valuation is fully reflected in the stock price, if we recognize deterioration in thesis or a change in catalysts, or if an alternate stock with superior attributes has been identified.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Growth Style Investment Risk.</b> Growth stocks may be more expensive relative to the values of other stocks and carry potential for significant volatility and loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>

Fees and Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the aggregate in specified classes of certain <i>Wells Fargo Advantage Funds</i>

More information about these and other discounts is available from your financial professional and in "A Choice of Share Classes" and "Reductions and Waivers of Sales Charges" on pages 41 and 43 of the Prospectus and "Additional Purchase and Redemption Information" on page 48 of the Statement of Additional Information.</p>

Example of Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that operating expenses remain the same as in the tables above. The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>

Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 32% of the average value of its portfolio.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small- and medium-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-and medium capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small- and medium-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small and medium capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>

<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Currency Transactions Risk</b>. Foreign securities are often denominated in foreign currencies. As a result, the value of a Fund's shares is affected by changes in exchange rates. Use of hedging techniques cannot protect against exchange rate risk perfectly. If the Fund's adviser is incorrect in its judgment of future exchange rate relationships, the Fund could be in a less advantageous position than if such a hedge had not been established.</p>

<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>

<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>

Fees and Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the aggregate in specified classes of certain <i>Wells Fargo Advantage Funds</i>
®. More information about these and other discounts is available from your financial professional and in "A Choice of Share Classes" and "Reductions and Waivers of Sales Charges" on pages 41 and 43 of the Prospectus and "Additional Purchase and Redemption Information" on page 48 of the Statement of Additional Information.</p>

Example of Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that operating expenses remain the same as in the tables above. The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>

Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 33% of the average value of its portfolio.</p>

Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We utilize a long-term focus that is intended to take advantage of investment opportunities presented by what we believe are short-term price anomalies in high-quality stocks. We seek to identify companies with established operating histories, financial strength and management expertise, among other factors. We seek stocks that are trading at a discount to what we believe are their estimated intrinsic values. Fundamental research is performed to identify securities for the portfolio with one or more catalysts present that will unlock the intrinsic value of the securities. These catalysts may include productive use of strong free cash flow, productivity gains, positive change in management or control, innovative or competitively superior products, increasing shareholder focus, or resolution of ancillary problems or misperceptions. We may sell a holding if the value potential is realized, if warning signs emerge of beginning fundamental deterioration or if the value is no longer compelling relative to the alternatives. We may invest in any sector, and at times we may emphasize one or more particular sectors.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Sector Emphasis Risk.</b> Investing a substantial portion of the Fund's assets in related industries or sectors may have greater risks because companies in these sectors may share common characteristics and may react similarly to market developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Value Style Investment Risk.</b> Value stocks may lose value and may be subject to prolonged depressed valuations.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We look for significantly undervalued companies that we believe have the potential for above average capital growth with below average risk. Rigorous fundamental research drives our search for undervalued, high quality companies; which we define as industry leaders with strong balance sheets and superior cash flows. We utilize quantitative screens to narrow the investment universe by assessing companies' financial statement strength and looking for high cash flows and low financial leverage. Through detailed qualitative research we then identify stocks valued below their estimated intrinsic value with hidden opportunities for above-average appreciation. Typical investments include stocks of companies that have low price-to-earnings ratios, are generally out of favor in the marketplace, are selling significantly below their stated or replacement book value or are undergoing a reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock's price nears its intrinsic value appreciation target, the macro environment becomes unfavorable, short-term downside risks increase, the company's fundamentals have deteriorated or we identify a more attractive investment opportunity.</p>

Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over"its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 57% of the average value of its portfolio.</p>

Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small-capitalization companies.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations, at the time of purchase, within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was $101 million to $2.608 billion, as of May 31, 2012, and is expected to change frequently. </p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The core of our research process is the rigorous analysis of each portfolio candidate to identify superior opportunities in each of three categories: First, we develop a strong multi-year investment thesis for each company. Next, we identify catalysts that will drive long-term sustainable earnings growth in excess of current market expectations. Lastly, we look for attractive valuations that do not fully reflect the company's long term growth potential. Once each of these three categories is satisfied (thesis, catalysts, and valuation), a company is added to the portfolio. We sell stocks if our thesis or valuation is fully reflected in the stock price, if we recognize deterioration in thesis or a change in catalysts, or if an alternate stock with superior attributes has been identified.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Growth Style Investment Risk.</b> Growth stocks may be more expensive relative to the values of other stocks and carry potential for significant volatility and loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small- and medium-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-and medium capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small- and medium-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small and medium capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>

The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 16% of the average value of its portfolio.</p>

Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Currency Transactions Risk</b>. Foreign securities are often denominated in foreign currencies. As a result, the value of a Fund's shares is affected by changes in exchange rates. Use of hedging techniques cannot protect against exchange rate risk perfectly. If the Fund's adviser is incorrect in its judgment of future exchange rate relationships, the Fund could be in a less advantageous position than if such a hedge had not been established.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Value Style Investment Risk.</b> Value stocks may lose value and may be subject to prolonged depressed valuations.</p>

<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We utilize a long-term focus that is intended to take advantage of investment opportunities presented by what we believe are short-term price anomalies in high-quality stocks. We seek to identify companies with established operating histories, financial strength and management expertise, among other factors. We seek stocks that are trading at a discount to what we believe are their estimated intrinsic values. Fundamental research is performed to identify securities for the portfolio with one or more catalysts present that will unlock the intrinsic value of the securities. These catalysts may include productive use of strong free cash flow, productivity gains, positive change in management or control, innovative or competitively superior products, increasing shareholder focus, or resolution of ancillary problems or misperceptions. We may sell a holding if the value potential is realized, if warning signs emerge of beginning fundamental deterioration or if the value is no longer compelling relative to the alternatives. We may invest in any sector, and at times we may emphasize one or more particular sectors.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We look for significantly undervalued companies that we believe have the potential for above average capital growth with below average risk. Rigorous fundamental research drives our search for undervalued, high quality companies; which we define as industry leaders with strong balance sheets and superior cash flows. We utilize quantitative screens to narrow the investment universe by assessing companies' financial statement strength and looking for high cash flows and low financial leverage. Through detailed qualitative research we then identify stocks valued below their estimated intrinsic value with hidden opportunities for above-average appreciation. Typical investments include stocks of companies that have low price-to-earnings ratios, are generally out of favor in the marketplace, are selling significantly below their stated or replacement book value or are undergoing a reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock's price nears its intrinsic value appreciation target, the macro environment becomes unfavorable, short-term downside risks increase, the company's fundamentals have deteriorated or we identify a more attractive investment opportunity.</p>

Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions,when it buys and sells securities (or "turns over"its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small-capitalization companies.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations, at the time of purchase, within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was $101 million to $2.608 billion, as of May 31, 2012, and is expected to change frequently. </p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The core of our research process is the rigorous analysis of each portfolio candidate to identify superior opportunities in each of three categories: First, we develop a strong multi-year investment thesis for each company. Next, we identify catalysts that will drive long-term sustainable earnings growth in excess of current market expectations. Lastly, we look for attractive valuations that do not fully reflect the company's long term growth potential. Once each of these three categories is satisfied (thesis, catalysts, and valuation), a company is added to the portfolio. We sell stocks if our thesis or valuation is fully reflected in the stock price, if we recognize deterioration in thesis or a change in catalysts, or if an alternate stock with superior attributes has been identified.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Growth Style Investment Risk.</b> Growth stocks may be more expensive relative to the values of other stocks and carry potential for significant volatility and loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small- and medium-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-and medium capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small- and medium-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small and medium capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Value Style Investment Risk.</b> Value stocks may lose value and may be subject to prolonged depressed valuations.</p>

<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets in equity securities of small-capitalization companies; and</p>
</li><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.</p>

Principal Investment Risks
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and is primarily subject to the risks briefly summarized below.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Counter-Party Risk.</b> A Fund may incur a loss if the other party to an investment contract, such as a derivative or a repurchase or reverse repurchase agreement, fails to fulfill its contractual obligation to the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Derivatives Risk.</b> The use of derivatives such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than offset risk.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Currency Transactions Risk</b>. Foreign securities are often denominated in foreign currencies. As a result, the value of a Fund's shares is affected by changes in exchange rates. Use of hedging techniques cannot protect against exchange rate risk perfectly. If the Fund's adviser is incorrect in its judgment of future exchange rate relationships, the Fund could be in a less advantageous position than if such a hedge had not been established.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Foreign Investment Risk.</b> Foreign investments face the potential of heightened illiquidity, greater price volatility and adverse effects of political, regulatory, tax, currency, economic or other macroeconomic developments.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Issuer Risk.</b> The value of a security may decline because of adverse events or circumstances that directly relate to conditions at the issuer or any entity providing it credit or liquidity support.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Leverage Risk.</b> Leverage created by borrowing or certain investments, such as derivatives and reverse repurchase agreements, can diminish the Fund's performance and increase the volatility of the Fund's net asset value.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Liquidity Risk.</b> A security may not be able to be sold at the time desired or without adversely affecting the price.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Management Risk.</b> There is no guarantee of the Fund's performance or that the Fund will meet its objective. The market value of your investment may decline and you may suffer investment loss.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Market Risk.</b> The market price of securities owned by the Fund may rapidly or unpredictably decline due to factors affecting securities markets generally or particular industries.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Options Risk.</b> An investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves. A Fund that purchases options is subject to the risk of a complete loss of premiums, while a Fund that writes options could be in a worse position than it would have been had it not written the option. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Regulatory Risk.</b> Changes in government regulations may adversely affect the value of a security. An insufficiently regulated industry or market might also permit inappropriate practices that adversely affect an investment.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Smaller Company Securities Risk.</b> Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than larger company stocks.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Value Style Investment Risk.</b> Value stocks may lose value and may be subject to prolonged depressed valuations.</p>

Investment Objective
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund seeks long-term capital appreciation.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Fees and Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>Shareholder Fees (fees paid directly from your investment) </b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) </b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Example of Expenses
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that operating expenses remain the same as in the tables above. The example also assumes that the Total Annual Fund Operating Expenses After Fee Waiver shown above will only be in place for the length of the current waiver commitment. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;"><b>
Portfolio Turnover
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 33% of the average value of its portfolio.</p>

Principal Investment Strategies
</b></p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">Under normal circumstances, we invest:</p>
<ul><li>
<p style="font-size:12;padding-top:0;padding-bottom:0;padding-left:0;">at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.</p>
</li></ul>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500™ Index at the time of purchase. The market capitalization range of the Russell 2500™ Index was $101 million to $6.345 billion, as of May 31, 2012, and is expected to change frequently.</p>
<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">We utilize a long-term focus that is intended to take advantage of investment opportunities presented by what we believe are short-term price anomalies in high-quality stocks. We seek to identify companies with established operating histories, financial strength and management expertise, among other factors. We seek stocks that are trading at a discount to what we believe are their estimated intrinsic values. Fundamental research is performed to identify securities for the portfolio with one or more catalysts present that will unlock the intrinsic value of the securities. These catalysts may include productive use of strong free cash flow, productivity gains, positive change in management or control, innovative or competitively superior products, increasing shareholder focus, or resolution of ancillary problems or misperceptions. We may sell a holding if the value potential is realized, if warning signs emerge of beginning fundamental deterioration or if the value is no longer compelling relative to the alternatives. We may invest in any sector, and at times we may emphasize one or more particular sectors.</p>

<p style="font-size:12;padding-top:2;padding-bottom:0;padding-left:0;">
<b>Sector Emphasis Risk.</b> Investing a substantial portion of the Fund's assets in related industries or sectors may have greater risks because companies in these sectors may share common characteristics and may react similarly to market developments.</p>
